Before further flight after any action is required by Requirement 2 of this Airworthiness Directive. This Amendment becomes effective on 28 September 2006. Background: This Airworthiness Directive is the result of service difficulty reports related to the collapse or involuntary retraction of the nose landing gear (NLG). The actions specified in this Airworthiness Directive are intended to detect, correct, and prevent failure in certain components of the NLG, lack of cleanliness of the NLG due to inadequate maintenance, or lack of lubricant in the NLG or NLG components. This failure of the NLG could lead to loss of control of the airplane during take-off, landing, or taxiing operations. Amendment 1, effective 1 September 2005, introduced additional inspection requirements. This amendment updates the revision status of the Piper service bulletin and allows the use of later FAA approved revisions of this service bulletin when they become available. The original issue of this Airworthiness Directive became effective on 3 March 1994. David Villiers Delegate of the Civil Aviation Safety Authority 28 July 2006
